 Note

The following important changes were done as a part of MtoA 4.0.0. You can find more information about them here.

Autodesk Network Licensing now requires new license files with an updated 2020 version. Please follow the instructions on this page to generate your license file. More info about Arnold 6 licensing can be found here.

The default installation directory of Mtoa has been modified from this version to be installed within the Autodesk directory. Users will still have full control over installing to any directory of their choice. For example : Linux - /usr/autodesk/arnold Osx : /Applications/Autodesk/Arnold and Windows C:/Program Files/Autodesk/Arnold/

 

MtoA 4.0.1 is a feature release, that is binary compatible with 4.0.* versions. It includes the following improvements:

Enhancements

MaterialX shader: This adds a way for users to be able to assign a material encapsulated within a materialX file directly no the shape.

New aov_write_vector shader: This enables the writing of vector values into a vector typed AOV, for example for recording positional values. These would previously have been clamped when using rgb typed AOVs.

Progressive rendering improvements: Performance and memory consumption in progressive rendering mode has been improved in some render setups. These improvements currently require all outputs to either use box or closest filtering and is not compatible with deep drivers. The expected performance and memory improvement should be roughly proportional to your AA settings. (#9094)

Improvements to Import Arnold Shaders: The Import Arnold shaders workflow now also supports MaterialX (mtlx) files allowing users to import the file as a maya shading graph. Improvements have also been made to support more attribute connection types.

Incompatible Changes

OSX minimum version is now 10.11: We have raised the minimum version required for OSX from 10.9 to 10.11.
